    Sorin Teodor Popa (24 March 1953) is a Romanian American mathematician working on operator algebras. He is a professor at the University of California, Los Angeles.[1]

    Biography[edit]

    Popa earned his PhD from the University of Bucharest in 1983 under the supervision of Dan-Virgil Voiculescu, with thesis Studiul unor clase de subalgebre ale -algebrelor.[1][2] He has advised 15 doctoral students at UCLA, including Adrian Ioana.[2]

    Honors and awards[edit]

    In 1990, Popa was an invited speaker at the International Congress of Mathematicians (ICM) in Kyoto, where he gave a talk on "Subfactors and Classifications in von Neumann algebras". He was a Guggenheim Fellow in 1995.[3] In 2006, he gave a plenary lecture at the ICM in Madrid on "Deformation and Rigidity for group actions and Von Neumann Algebras".[4] In 2009, he was awarded the Ostrowski Prize,[1] and in 2010 the E. H. Moore Prize.[5] He is one of the inaugural fellows of the American Mathematical Society.[6] In 2013, he was elected to the American Academy of Arts and Sciences.
